HARRY GLASS, OF BLUE RIVER, WISCONSIN.

BOTTLE-CLOSURE.

To all whom it may concern:

Be it known that I, HARRY GLASS, a citizen of the United States, residing at Blue River, in the county of Grant and State of Wisconsin, have invented certain new and useful Improvements in Bottle-Closures, of which the following is a specification, reference being had tothe accompanying drawm s.

This invention relates to bottle closures and has for its object to provide a device of very simple construction which will facilitate the filling of the bottle and is adapted to be securely sealed therein so that in order to dispense the contents of the bottle it is necessary to break the end of the bottle neck, thereby rendering the bottle unavailable for commercial use.

The invention consists in the construction and arrangement of parts, as will be hereinafter described and particularly pointed out in the claim.

Figure 1 is a longitudinal section of the neck portion of the bottle showing my improved closure arranged therein; Fig. 2 is a section taken on the line 2-2 of Fig. l; and Fig. 3 is a detail perspective view of the filling tube.

Referring in detail to the drawing 5 designates a bottle or other vessel formed of glass and having a neck 6 which is scored as indicated at 7 to weaken the same. The upper end of the neck of the bottle is preferably funnel-shaped as shown at 8 and within said neck a gasket 9 is arranged. This gasket extends above and below the contracted portion of the neck at which the same is scored as clearly shown in Fig. 1 and is engaged closely with the inner wall of the bottle neck. A glass tube 10 is inserted into the neck of the bottle and is also formed with a flared or funnel-shaped end 11 which engages closely within the upper end of the gasket 9. This tube is provided for the purpose of conveniently filling the bottle or other receptacle without wetting the cork gasket 9 with the liquid. It will be obvious that if the liquid was poured into the vessel directly upon this gasket, the cork would absorb a considerable quantity thereof so that it would enlarge and lose its proper shape in order to retain its position within the neck of the receptacle, whereby when contraction of the cork takes place, the gasket would fall into the liquid contained 1n the vessel. After the vessel has been Specification of Letters Patent.

Application filed March 13, 1911.

filled, the flared or bell-shaped end 11 of the tube will act to retain the gasket in its proper form. This gasket is preferably of cork and serves to prevent accidental breakage of the end of the bottle neck through careless handling of the bottle. The tube 10 is provided with a vent opening 12 which. permits of the escape of air from the bottle as the liquid is poured into the same through said tube. A metal cap 13 is placed over the open end of the bottle neck and is securely sealed thereon in such manner, that any attempt to remove the cap from the bottle neck will cause the neck to break at the scored or weakened portion 7 thereof. This breaking of the bottle neck will render the same unavailable for further commercial use as it will at once indicate to the intending purchaser that the original contents of the bottle have been removed.

The gasket 9 serves to retain the inner tube 10 in its proper position within the bottle to prevent the same being broken, said gasket also preventing accidental breakage of the bottle neck. It will be observed that the inner surface of the lower flared end of the gasket 9 is spaced from the periphery of the tube 10, so that when said gasket eX- pands by the absorption of fluid, there will be no liability of the fracture of said tube or of the breakage of the bottle neck at the score 7. hen, however, it is desired to dispense the contents of the bottle, the end of the bottle neck is struck a sharp blow and the same broken off at the scored or weakened portion 7. The broken end of the bottle neck is then removed together with the gasket 9 and tube 10. It will further be noted that the gasket will prevent the liability of particles of glass falling into the bottle or other receptacle, thereby obviating liability of injury to the health of the consumer.

From the foregoing it is thought that the construction and operation of my invention will be readily understood without requiring a more extended description.

Owing to the fact that but few elements are employed in the construction, the device may be manufactured at small cost and is furthermore extremely eflicient in practical use.

Having thus described the invention what is claimed is:

A bottle comprising the neck port-ion with a circumferential score therearound, the

terminal of the neck being beaded and flaring, a flexible concavo-convex shaped gasket mounted in the neck and having a reduced upper and lower end, said gasket adapted to 5 contact With the neck and its flaring portion, a tube having a vent opening therein and provided With a flaring upper end, said tube being mounted in the gasket and projecting into the body of the bottle with its flaring 10 upper end contacting With the reduced upper end of the gasket, and means connected to the bead so as to close the flaring end of the tube.

In testimony whereof I hereunto affix my signature in the presence of two Witnesses. 15
